/* ==========================================================================
   Hero film (Home only, loaded through pageCss). Added 24 Oct 2026.
   A silent looping preview fills the hero image column; a gold play button
   opens the full film with sound in a dialog with branded controls.
   Uses only the tokens in site.css. See DESIGN.md "Hero film".
